The Alley Tramp (1968)

Sixteen year old Marie stumbles upon her parents making love, which awakens her latent sexuality. She begins a torrid affair with her third cousin Philip. Her parents cluelessly pursue their own illicit affairs while their daughter delves deeper into her own sexual experimentation. When the school principal makes the Barkers aware that their daughter is cutting classes, they purchase a partial clue and try to help their daughter.

Horror master Hershell Gordon Lewis took a break from the gore and went for sex and nudity in this over the top sex comedy. The film tells the story of a 16-year-old girl who catches her parents having sex so she rushes to her third cousin and the two begin sleeping around. Although she's in love, the teenage girl wants sex with more men and that includes her mother's secret lover. I'm sure this type of trash played all over 42nd Street in various Grindhouse theaters and on that level the film is a minor success. As you'd expect, the acting is laughably bad as is the script but laughter is good in these types of films. When the girl seduces her cousin it's rather sexy and hilarious at the same time. There's also some hilarious moments with the girl's father as he tries to avoid having sex with his wife. There's plenty of T&A from the mother and daughter so if you like trashy fun then this should be right up your alley.
